The most dangerous of devotions, in my opinion, is the one endemic to Christianity: I was not born to be of this world. With a second life waiting, suffering can be endured - especially in other people. The natural environment can be used up. Enemies of the faith can be savaged and suicidal martyrdom praised.

The time has come to link ecology to economic and human development. When you have seen one ant, one bird, one tree, you have not seen them all. What is happening to the rain forests of Madagascar and Brazil will affect us all.

In the early stages of creation of both art and science, everything in the mind is a story.

Somewhere close I knew spear-nosed bats flew through the tree crowns in search of fruit, palm vipers coiled in ambush in the roots of orchids, jaguars walked the river's edge; around them eight hundred species of trees stood, more than are native to all of North America; and a thousand species of butterflies, 6 percent of the entire world fauna, waited for the dawn.

I grew up as a Southern Baptist with strict adherence to the Bible, which I read as a youngster.

We don't know nearly enough about the complexities of Nature. If we think we can eliminate natural ecosystems and substitute prosthetic devices, i.e. clean air or water with fusion energy - we are kidding ourselves.

Homo sapiens, the first truly free species, is about to decommission natural selection, the force that made us. Soon we must look deep within ourselves and decide what we wish to become.
